v3.2.4

Added

• Build identity in the startup banner, /status footer, and startup log line. When running from source ahead of the latest release tag (or with uncommitted edits), these now show e.g. v3.2.4 (build v3.2.3-4-g129acde[-dirty]) so it's clear exactly which commit is running — not just the last release number. Derived from git describe --tags --always --dirty at startup; on an exact tagged release it collapses to the clean tag (no suffix), and if git isn't available (e.g. a zip download) it falls back to __version__ alone. __version__ remains the authoritative release number for the changelog, releases, and the HTTP User-Agent (which stay clean semver).
